TECHNICAL FIELD

This disclosure relates to the field of communication technologies, andin particular to a resource configuration method, a resourcedetermination method, apparatuses thereof and a communication system.

BACKGROUND

In future wireless communication systems, such as 5G and New Radio (NR)systems, a network side configures a control resource set (CORESET) fora user equipment (UE). After performing beam sweeping at a UE side, aphysical downlink control channel (PDCCH) in the control resource setneeds to be detected. Downlink data carried by a physical downlinkshared channel (PDSCH) are received or uplink data carried by a physicaluplink shared channel (PUSCH) are transmitted according to a schedulingindication unit of the detected PDCCH.

It should be noted that the above description of the background ismerely provided for clear and complete explanation of this disclosureand for easy understanding by those skilled in the art. And it shouldnot be understood that the above technical solution is known to thoseskilled in the art as it is described in the background of thisdisclosure.

SUMMARY

In the current discussion, some control resources may be used via aPDSCH to obtain higher frequency efficiency and/or lower latency. Thus,after the above CORESET is configured, some additional resource sets maybe configured for the UE. Furthermore, whether an operation executed onthe above CORESET and the additional resource sets is “rate matching” or“data mapping” is indicated by downlink control information in a PDCCH.

In the current discussion, the above-described additional resource setsare UE-specific configuration, that is, the additional resource setscorrespond to a specific UE. Therefore, when the UE is configured todetect multiple CORESETs, downlink control information in a PDCCH ineach CORESET needs to indicate all the above additional resource setsconfigured for the UE.

However, since resources scheduled by the PDCCH in each CORESET may bedifferent, the above indication mode will increase the overhead of thedownlink control information.

As shown in FIG. 1, two control resource sets,CORESET #1 and CORESET #2, which need to be detected, and additionalresource sets, Resource set #1, Resource set #2 and Resource set #3, areconfigured by a network side for the UE; the UE respectively detectsPDCCH #1 and PDCCH #2 possibly occurring in CORESET #1 and CORESET #2,and operations executed on CORESET #1 and CORESET #2 as well as Resourceset #1, Resource set #2 and Resource set #3 need to be indicated byPDCCH #1 and PDCCH #2; however, for PDCCH #2 in CORESET #2, as positionsof CORESET #1 and Resource set #1 are prior to its position, resourcesscheduled by it will not include CORESET #1 and Resource set #1, and ifdownlink control information in PDCCH #2 is still directed to theUE-specific configured additional resource sets, 2 bits in a bitmap inthe downlink control information will be wasted.

In the embodiments of this disclosure, by configuring one or moreadditional resource sets corresponding to each control resource set oreach group of control resource sets, that is, by specificallyconfiguring additional resource sets for the control resource sets,payload of downlink control information may be reduced, and currentlyexisted problems may be solved.

The embodiments of this disclosure shall be described below withreference to the accompanying drawings.

Embodiment 1

FIG. 2 is a flowchart of the resource configuration method in Embodiment1, which is applicable to a network device side. As shown in FIG. 2, themethod includes:

step 201: a network device side configures one or more additionalresource sets corresponding to each control resource set or each groupof control resource sets.

It can be seen from the above embodiment that by configuring one or moreadditional resource sets corresponding to each control resource set oreach group of control resource sets, that is, by specificallyconfiguring additional resource sets for the control resource sets,payload of downlink control information may be reduced, and currentlyexisted problems may be solved.

In an embodiment, the method further includes (not shown): the networkside configures for the user equipment a control resource set needing tobe detected, so that the user equipment obtains scheduling dataaccording to the configured control resource set; each user equipmentmay be configured with one or more control resource sets, time-domainand frequency-domain size and/or position of each control resource setbeing able to be configured as needed.

For example, the size of each control resource set includes the numberof symbols and control channel elements (CCEs); for example, the size ofeach control resource set may be configured as being one symbol and 16CCEs; the time-domain and frequency-domain position of each controlresource set includes symbols in a control region of a correspondingslot; for example, a particular time-domain and frequency-domainposition may be configured as being M symbols in the corresponding slot(such as former first, second and third symbols). These are illustrativeonly, and this embodiment is not limited thereto.

In an embodiment, the additional resource set may include all or part ofcontrol resources in control resource sets configured for one or moreother UEs; and furthermore, it may include other resources, such asresources for transmitting data on a PDSCH and a PUSCH; however, thisembodiment is not limited thereto. And higher frequency efficiencyand/or lower latency may be obtained via the additional resource set.

In an embodiment, the network side may configure the control resourceset and the corresponding additional resource set at the same time, ormay configure the control resource set first, and then configure theadditional resource set corresponding thereto, and this embodiment isnot limited thereto.

In one embodiment, one or more additional resource sets corresponding toeach control resource set may be configured, that is, for differentCORESETs, one or more additional resource sets corresponding thereto areconfigured.

For example, the network side configures n CORESETs needing to bedetected for the UE, which are CORESET #m₁, CORESET #m₂, . . . , CORESET#m_(n); where, n is an integer greater than or equal to 1, and m_(n)denotes an index of the CORESET. The network side configures anadditional resource set for each CORESET, as shown in Table 1 below. Forexample, additional resource sets configured for a CORESET with an indexm, are Resource set # m_(i, 1), Resource set #m_(i, 2) . . . Resourceset #m_(i, ki), a value range of i being 1˜n.

TABLE 1 CORESET Configured additional resource set #m₁ Resource set#m_(1,1), Resource set #m_(1,2) . . . Resource set #m_(1,k1) #m₂Resource set #m_(2,1), Resource set #_(2,2) . . . Resource set #m_(2,k2). . . . . . #m_(i) Resource set #m_(i,1), Resource set #m_(i,2) . . .Resource set #m_(i,ki) . . . . . . #m_(n) Resource set #m_(n,1),Resource set #m_(n,2) . . . Resource set #m_(n,kn)

where, k1, k2, ki, . . . , kn are integers greater than or equal to 1,and may be identical or may be different.

FIGS. 3A and 3B are schematic diagrams of configuring additionalresource sets based on CORESETs. As shown in FIGS. 3A and 3B, twoCORESETs needing to be detected are configured for the UE, which areCORESET #1 and CORESET #2, respectively. As shown in FIG. 3A, theadditional resource sets configured for CORESET #1 are Resource set #1,Resource set #2 and Resource set #3. And as shown in FIG. 3B, theadditional resource set configured for CORESET #2 is Resource set #3.

In one embodiment, one or more additional resource sets corresponding toeach group of control resource sets may be configured, that is, fordifferent groups of CORESETs, one or more additional resource setscorresponding to the groups of CORESETs are configured.

For example, the network side configures the UE with n CORESETs needingto be detected, which are CORESET #m₁, CORESET #m₂, . . . , CORESET#m_(n). The n CORESETs are divided into p groups. Second group indicesof each group are #1, #2, . . . , #p, p being an integer greater than orequal to 1. The number of CORESETs in each group may be identical ordifferent, as shown in Table 2 below. For example, CORESETs close toeach other in the time domain and the frequency domain may be dividedinto a group; however, this embodiment is not limited thereto.

TABLE 2 Second group indices CORESETs in a group #1 CORESET #m₁, . . . ,CORESET #m_(a) . . . . . . #j CORESET #m_(b), . . . , CORESET #m_(c) . .. . . . #p CORESET #m_(d), . . . , CORESET #m_(n)

where, a, b, c and d are integers greater than 1, and are different fromeach other.

The network side configures additional resource sets for the p groupsCORESETs, as shown in Table 3 below. For example, additional resourcesets configured for a CORESET with a second group index #j are Resourceset #m_(j,1), Resource set #m_(j,2) . . . Resource set #m_(j,rj), avalue range of j being 1˜p.

TABLE 3 Second group indices of groups of CORESETs Configured additionalresource sets #1 Resource set #m_(1,1), Resource set #m_(1,2) . . .Resource set #m_(1,r1) . . . . . . #j Resource set #m_(j,1), Resourceset #m_(j,2) . . . Resource set #m_(j,rj) . . . . . . #p Resource set#m_(p,1), Resource set #m_(p,2) . . . Resource set #m_(p,rp)

where, r1, r2, . . . , rp are integers greater than 1, and may beidentical to or different from each other.

For example, three CORESETs needing to be detected, CORESET #1, CORESET#2 and CORESET #3, are configured for the UE, which are divided into twogroups (p=2), such as dividing CORESET #1 and CORESET #2 into a group(with a second group index #1), and CORESET #3 is divided into a group(with a second group index #2); and additional resource sets configuredfor the first group CORESET #1 and CORESET #2 are Resource set #1,Resource set #2 and Resource set #3 (r1=3), and an additional resourceset configured for the second group CORESET #3 is Resource set #3(r2=1).

In an embodiment, after the additional resource sets are configured bythe network side, the configured additional resource sets may benotified to the user equipment. For example, information on theadditional resource sets may be transmitted to the user equipment viahigher-layer signaling, such as radio resource control (RRC) signaling.

In an embodiment, an information element (IE) of the radio resourcecontrol signaling contains information on each control resource set oreach group of control resource sets, and information on one or moreadditional resource sets configured corresponding to each controlresource set or each group of control resources. The information is usedto identify the control resource sets and the additional resource sets,for example, the information may be information for identifyingpositions of the control resource sets and the additional resource sets,such as the number and position of time-domain symbols (e.g. OFDMsymbols), and resource block information in the frequency domain (e.g. aphysical resource block (PRB) number, and a frequency offset), etc. Andfurthermore, the information may also include an index of a resourceset.

In one embodiment, when one or more additional resource setscorresponding to each control resource set are configured, an IE formatin the RRC is as shown in the following format (1):

CORESET #m₁, Resource set #m_(1,1), #m_(1,2), . . . , #m_(1,k1),

CORESET #m₂, Resource set #m_(2,1), #m_(2,2), . . . , #m_(2,2),

. . .

CORESET #m_(n), Resource set #m_(n,1), #m_(n,2), . . . , #m_(n,kn).

Format (1) indicates that configured additional resource sets forCORESET #m₁ are Resource set #m_(1,1), #m_(1,2) . . . #m_(1,k1),configured additional resource sets for CORESET #m₂ are Resource set#m_(2,1), #m_(2,2) . . . #m_(2,k2), and configured additional resourcesets for CORESET #m_(n), are Resource set #m_(n,1), #m_(n,2) . . .#m_(n,kn); where, n denotes the number of CORESETs configured for theUE, #mn denotes indices of the CORESETs, kn denotes the number ofadditional resource sets configured for a CORESET, and #m_(n, 1),#m_(n, 2) . . . #m_(n, kn), denote indices of the additional resourcesets.

It should be noted that in an IE, information on indices of the resourcesets may not be included, and the above resource sets may be arranged byusing a predetermined rule. For example, the IE may not include theindices of the CORESETs, and the above control resource sets and theadditional resource sets corresponding thereto may be sequentiallyarranged according to an ascending or descending order of the indices;however, this embodiment is not limited thereto.

In one embodiment, when one or more additional resource setscorresponding to each group of control resource sets are configured, anIE format in the RRC is as shown in the following format (2):

CORESET #m₁, . . . , #m_(a), Resource set #m_(1,1), #m_(1,2), . . . ,#m_(1,r1),

. . .

CORESET #m_(b), . . . , #m_(c), Resource set #m_(j,1), #m_(j,2), . . . ,#m_(j,rj),

. . .

CORESET #m_(d), . . . , #m_(n), Resource set #m_(p,1), #_(p,2), . . . ,#m_(p,rp).

Format (2) indicates that n CORESETs are divided into p groups.Configured additional resource sets for a group of CORESETs #m₁, . . . ,#m_(a) are Resource set #m_(1,1), #m_(1,2) . . . #m_(1,r1), configuredadditional resource sets for a group of CORESETs #m_(b), . . . , #m_(c)are Resource set #m_(j,1), #m_(j,2) . . . #m_(j,rj), and configuredadditional resource sets for a group of CORESETs #m_(d), . . . , #m_(n),are Resource set #m_(p,1), #m_(p,2) . . . #m_(p,rp); where, n denotesthe number of CORESETs configured for the UE, #m_(n) denotes indices ofthe CORESETs, rj denotes the number of additional resource setsconfigured for one group (with a second group index #j) of CORESETs, and#m_(j,1), #m_(j,2) . . . #m_(j,rj) denote indices of the additionalresource sets configured for the group #j.

It should be noted that in an IE, information on indices of the resourcesets may not be included, and the above resource sets may be arranged byusing a predetermined rule. For example, the IE may not include theindices of the CORESETs, and the above control resource sets and theadditional resource sets corresponding thereto may be sequentiallyarranged according to an ascending or descending order of the secondgroup indices of the p groups of CORESETs; however, this embodiment isnot limited thereto. Alternatively, the IE may not include the indicesof the CORESETs, but include indices of the second group where theCORESETs are located. For example, an IE format in the RRC is as shownin the following format (3):

CORESET (second group index #1), Resource set #m_(1,1), #m_(1,2), . . ., #m_(1,s1),

. . .

CORESET (second group index #j), Resource set #m_(j,1), #m_(j,2), . . ., #m_(j,sj),

. . .

CORESET (second group index #p), Resource set #m_(p,1), #m_(p,2), . . ., #m_(p,sp).

The network side may notify the user equipment the second groupinginformation. When the user equipment receives the RRC information, itdetermines the additional resource sets configured for each group ofCORESETs according to the IE therein, also may determine CORESETs ineach CORESET group, and hence determine additional resource setscorresponding to each CORESET.

In an embodiment, the configured additional resource sets may obtainhigher frequency efficiency and/or lower latency, and operationsperformed on these additional resource sets may further be indicated.Hence, in this embodiment, the method may further include: step 202(optional): the network device side configures indication informationindicating operations performed on the additional resource sets, orindication information indicating operations performed on the controlresource sets and the additional resource sets.

The executed operations include rate matching or data mapping. When theperformed operations are data mapping, it indicates that a PDSCHscheduled by the UE may perform data mapping processing on the resource.And when the performed operations are rate matching, it indicates thatthe resource cannot be used by the UE for data mapping processing, andthe scheduled PDSCH can only perform rate matching around thetime-frequency position of the resource. For example, when theadditional resource sets include PDCCHs detected by other UEs,operations performed on the additional resource sets may be ratematching; otherwise, they may be data mapping; however, this embodimentis not limited thereto. Reference may be made to the relevant art forparticular operations of data mapping and rate matching, which shall notbe described herein any further.

In an embodiment, the indication information may be transmitted via aphysical downlink channel in the control resource sets, the indicationinformation may be a second predetermined number of bits, and theindication may be performed in a bitmap manner.

When the indication information is used to indicate the operationsperformed on the additional resource sets, the second predeterminednumber is equal to the number of the additional resource setscorresponding to a control resource set or a group of control resourcesets, or the second predetermined number is equal to a maximum value inthe number of different additional resource sets corresponding todifferent control resource sets or different groups of control resourcesets.—

Each bit in the second predetermined number of bits respectivelyindicate an operation performed on one or more additional resource setsconfigured corresponding to each control resource set or each group ofcontrol resource sets.

For example, for the additional resource set configured for the aboveformat (1), for CORESET #m_(i), the number of configured additionalresource sets is ki, and the indication information is carried bydownlink control information (DCI) of a PDCCH in CORESET #m_(i). Thenumber of bits of the indication information (the second predeterminednumber) is equal to ki, and each bit respectively indicates operationsperformed on Resource set #mi_(,1), m_(i,2) . . . #m_(i,ki); or thenumber of bits of the indication information (the second predeterminednumber) is equal to a maximum value in k1, k2, . . . , ki, . . . , kn,thus, lengths of DCI of PDCCHs in each CORESET remain identical.

For example, for the additional resource set configured in the format(2) above, for the control resource set with a second group index #j,the indication information is carried by DCI of a PDCCH of the controlresource set with the second group index #j. The number of bits of theindication information (the second predetermined number) is equal to rj,and each bit respectively indicates operations performed on Resource set#m_(j,1), #m_(j,2) . . . #m_(j,rj); or the number of bits of theindication information (the second predetermined number) is equal to amaximum value in r1, r2, . . . , rj, . . . , rp, thus, lengths of DCI ofPDCCHs in each CORESET remain identical. For the additional resourcesets configured for above format (2), its indication mode is similar toformat (2), which shall not be described herein any further.

When the indication information is used to indicate operations performedon the control resource sets and the additional resource sets, thesecond predetermined number is equal to the number of the additionalresource sets corresponding to each control resource set or each groupof control resource sets plus 1, or is equal to the number of thecorresponding additional resource sets plus the number of controlresource sets in a group of control resource sets, or the secondpredetermined number is equal to a maximum value in the number ofdifferent additional resource sets corresponding to different controlresource sets or different groups of control resource sets plus 1, or isequal to a maximum value in the number of different additional resourcesets plus the number of control resource sets in a group of controlresource sets.

Each bit in the second predetermined number of bits respectivelycorrespondingly indicates operations performed on each control resourceset or each group of control resource sets and the one or moreadditional resource sets configured corresponding to each controlresource set or each group of control resource sets.

For example, for the additional resource set configured for the aboveformat (1), for CORESET #m_(i), the number of configured additionalresource sets is ki, the indication information is carried by DCI of aPDCCH in CORESET #m_(i), the number of bits of the indicationinformation (the second predetermined number) is equal to ki+1, and eachbit respectively indicates operations performed on CORESET #m_(i),Resource set #m_(i,1), #m_(i,2) . . . #m_(i,ki); or the number of bitsof the indication information (the second predetermined number) is equalto a maximum value in k1, k2, . . . ki, . . . , kn plus 1, thus, lengthsof DCI of PDCCHs in each CORESET remain identical.

For example, for the additional resource set configured for the aboveformat (2), for CORESETs with the second group index #j, the indicationinformation is carried by DCI of a PDCCH in the CORESETs with the secondgroup index #j, the number of bits of the indication information (thesecond predetermined number) is equal to rj+x, x being equal to thenumber of the CORESETs with the second group index #j, and each bitrespectively indicates operations performed on CORESET #m_(b), . . . ,#m_(c), Resource set #m_(j,1), #m_(j,2) . . . #m_(j,rj); or the numberof bits of the indication information (the second predetermined number)is equal to a maximum value in r1, r2, . . . , rp plus x, thus, lengthsof DCI of PDCCHs in each CORESET remain identical.

For example, for the additional resource set configured for the aboveformat (3), for CORESETs with the second group index #j, the indicationinformation is carried by DCI of a PDCCH in the CORESETs with the secondgroup index #j, the number of bits of the indication information (thesecond predetermined number) is equal to sj+1, and each bit respectivelyindicates operations performed on the CORESETs with the second groupindex #j (indicating that operations performed on intra-group CORESETsare identical), Resource set #m_(j,1), #m_(j,2) . . . #m_(j,sj); or thenumber of bits of the indication information (the second predeterminednumber) is equal to a maximum value in s1, s2, . . . , sj, . . . , spplus 1, thus, lengths of DCI of PDCCHs in each CORESET remain identical.

As described above, when the second predetermined number is determinedaccording to the maximum value, it may be greater than the number P ofadditional resource sets configured for its control resource set, andoperations performed on the additional resource sets or on the controlresource sets and the additional resource sets may be respectivelyindicated according to P bits or P+1 or P+x bits in the secondpredetermined number of bits.

FIG. 4 is a schematic diagram of the configured additional resourcesets. As shown in FIG. 4, the configured additional resource setscorresponding to CORESET #1 are Resource set #1, Resource set #2,Resource set #3 and Resource set #4, and the indication information isconfigured to respectively indicate operations performed on CORESET #1,Resource set #1, Resource set #2, Resource set #3 and Resource set #4.The indication information is transmitted via downlink controlinformation of PDCCH #1 detected in CORESET #1.

For example, the indication information is 5-bits, and each bitrespectively correspondingly indicates operations performed on CORESET#1, Resource set #1, Resource set #2, Resource set #3 and Resource set#4 in turn; where, “0” denotes data mapping, and “1” denotes ratematching; however, this embodiment is not limited thereto, and viceversa.

As shown in FIG. 4, as PDCCH #2 exists in Resource set #3, the operationperformed on Resource set #3 is “rate matching”, and the operationsperformed on other resource sets are “data mapping”, the 5-bitsindication information may be expressed as 00010.

It should be noted that this embodiment is not limited thereto. Forexample, the CORESET may use a predetermined default operation, theindication information may be 4-bits, each bit respectively indicatesoperations performed on Resource set #1, Resource set #2, Resource set#3 and Resource set #4, and the 4-bits indication information may beexpressed as 0010.

It can be seen from the above embodiments that by configuring one ormore additional resource sets corresponding to each control resource setor each group of control resource sets, that is, by specificallyconfiguring additional resource sets for the control resource sets,payload of downlink control information may be reduced, and currentlyexisted problems may be solved.

Embodiment 2

FIG. 5 is a flowchart of the resource configuration method in Embodiment2, which is applicable to a network device side. As shown in FIG. 5, themethod includes:

step 501: a network device side configures one or more additionalresource sets corresponding to each control resource set or each groupof control resource sets.

In an embodiment, particular implementation of step 501 is identical tothat of step 201, which shall not be described herein any further. Whatis different from Embodiment 1 is that in this embodiment, the methodfurther includes:

step 502: the network device side divides all control resource sets of aUE and the one or more additional resource sets corresponding to eachcontrol resource set into a first predetermined number of groups; ordivides all control resource sets of UE and the one or more additionalresource sets corresponding to each group of control resource sets aredivided into a first predetermined number of groups.

In one embodiment, all the control resource sets of the UE and the oneor more additional resource sets corresponding to each control resourceset are divided into the first predetermined number of groups. Forexample, for the resource allocation mode in Table 1 above, all thetotal n+k1+k2+ . . . +kn resource sets in Table 1, CORESET #1, CORESET#m₂, . . . , CORESET #m_(n), Resource set #m_(1,1), #m_(1,2), . . .#m_(1,k1), Resource set #m_(2,1), #m_(2,2) . . . #m_(2,k2), . . . ,Resource set #m_(n,1), #m_(n,2) . . . #m_(n,kn), are divided into afirst predetermined number q groups.

In another embodiment, all the control resource sets of the UE and theone or more additional resource sets corresponding to each group ofcontrol resource sets are divided into a first predetermined number ofgroups. For example, for the resource allocation mode in Table 3 above,all the total n+r1+r2+ . . . +rj . . . +rp resource sets in Table 3,CORESET #m₂, CORESET #m₂, . . . , CORESET #m_(n), Resource set #m_(1,1),#m_(1,2), . . . #m_(1, r1), . . . , Resource set #m_(p,1), #m_(p,2) . .. #m_(p, rp), are divided into a first predetermined number q groups.

In an embodiment, the grouping may be performed according to differentinitial symbols and sizes of the CORESETs in step 502. However, thisembodiment is not limited thereto, and each group may include only thecontrol resource sets or only the additional resource sets, or includecontrol resource sets and additional resource sets, and the numbers ofcontrol resource sets and/or additional resource sets contained in thegroups may be identical or different. First group indices of the groupsare #1, #2, . . . , #q, respectively, and the first predeterminedquantity q may be determined as demanded; however, this embodiment isnot limited thereto.

In an embodiment, the method may further include (not shown): notifyingthe user equipment of the configured additional resource sets. Forexample, information on the additional resource sets may be transmittedto the user equipment via higher-layer signaling, such as radio resourcecontrol (RRC) signaling.

An information element of the radio resource control signaling includesinformation on each control resource set or each group of controlresource sets, and information on one or more additional resource setsconfigured corresponding to each control resource set or each group ofcontrol resource sets. Reference may be made to Embodiment 1 forparticular contents of the information, and reference may be made toEmbodiment 1 for particular formats of the information element thereof,such as those as shown in format (1), format (2), and format (3), whichshall not be described herein any further.

In an embodiment, the information element may further include a firstgroup index of a group where each control resource set or each group ofcontrol resource sets after being divided in step 502 is located, and afirst group index of a group where the one or more additional resourcesets configured corresponding to each control resource set or each groupof control resource sets is/are located.

For example, in format (1) of Embodiment 1, first group indices mayfurther be included, which are as shown below:

CORESET #m₁ (a first group index #1), Resource set #m_(1,1) (a firstgroup index #1), #m_(1,2) (a first group index #z), . . . , #m_(1, k1)(a first group index #q);

CORESET #m₂ (a first group index #2), Resource set #m_(2,1) (a firstgroup index #3), # m_(2,2) (a first group index #4), . . . , #m_(2, k2)(a first group index #q−1);

. . . ;

CORESET #m_(n) (a first group index #3), Resource set #m_(n,1) (a firstgroup index #4), #m_(n,2) (a first group index #t), . . . , #m_(n,kn) (afirst group index #q).

For example, in format (2) of Embodiment 1, first group indices mayfurther be included, which are as shown below:

CORESET #m₁ (a first group index #1), . . . , #m_(a) (a first groupindex #2), Resource set #m_(1,1) (a first group index #1), #m_(1,2) (afirst group index #1), . . . , #m_(1,r1) (a first group index #1),

. . . ;

CORESET #m_(b) (a first grouping index #2), . . . , #m_(c) (a firstgrouping index #3), Resource set #m_(j,1) (a first grouping index #3),#m_(j,2) (a first grouping index #3), . . . , #m_(j,rj) (a first groupindex #3),

. . . ;

CORESET #m_(d) (a first group index #t), . . . , #m_(n) (a first groupindex #z), Resource set #m_(p,1) (a first group index #q−1), #m_(p,2) (afirst group index #q), . . . , #m_(p,rp) (a first group index #q).

For example, in format (3) of Embodiment 1, group indices may also beincluded, which are as shown below:

CORESET (a second group index #1) (a first group index #1), Resource set#m_(1,1) (a first group index #1), #m_(1,2) (a first group index #2), .. . , #m_(1,s1) (a first group index #3),

. . . ;

CORESET (a second group index #j) (a first group index #t), Resource set#m_(j,1) (a first group index #1), #m_(j,2) (a first group index #z), .. . , #m_(j,sj) (a first group index #t),

. . . ;

CORESET (a second group index #p) (a first group index #q), Resource set#m_(p,1) (a first group index #3), #m_(p,2) (a first group index #t), .. . , #m_(p,sp) (a first group index #q).

The above indices 1, 2, 3, z, t, q−1, q of the first group where eachresource set is located are examples only, and this embodiment is notlimited thereto.

In an embodiment, the method may further include:

step 503: the network device side configures indication informationindicating operations performed on the control resource sets and theadditional resource sets.

In step 503, the indication information corresponding to groups may berespectively configured for the first predetermined number of groupsdivided in step 502. As the indication information is configured for thegroups, the operations performed on all resource sets in the group areidentical, which may further reduce the overhead of DCI and reduce thelength of the bitmap.

In an embodiment, particular meanings of the operations are as describedin Embodiment 1, which shall not be described herein any further.

In an embodiment, the indication information may be transmitted via aphysical downlink channel in the control resource sets; the indicationinformation may be a second predetermined number of bits, and may beindicated in by a bitmap; the second predetermined number is equal tothe first predetermined number, each bit of the second predeterminednumber of bits is used to indicate operations performed on a resourceset in the first predetermined number of groups, and the secondpredetermined number of bits respectively one by one correspond to thegroup indices.

For example, q bits are used to indicate operations performed on qgroups of resource sets, that is, a first bit in q bits indicates anoperation performed on a resource set with a first group index #1, asecond bit indicates an operation performed on a resource set with afirst group index #2, and a q-th bit indicates an operation performed ona resource set with a first group index #q; each bit may use 0 and 1 torespectively indicate that operations performed are data mapping or ratematching, and vice versa, and this embodiment is not limited thereto.

For example, the indication information is 010 . . . 1 and has total qbits, indicating that operations performed on the resource set with afirst group index #1 are data mapping, operations performed on theresource set with a first group index #2 are rate mapping, operationsperformed on the resource set with a first group index #3 are datamapping, . . . , and operations performed on the resource set with afirst group index #q are rate mapping.

It can be seen from the above embodiments that by configuring one ormore additional resource sets corresponding to each control resource setor each group of control resource sets, that is, by specificallyconfiguring additional resource sets for the control resource sets,payload of downlink control information may be reduced, and currentlyexisted problems may be solved.

Embodiment 3

step 603: the user equipment performs a corresponding operation on theone or more additional resource sets corresponding to each controlresource set or each group of control resource sets.

In an embodiment, before step 601, the method may further include (notshown): receiving information on the additional resources sets notifiedby the network device via RRC, reference being able to be made toembodiments 1 and 2 for a format of an information element in the RRC,which shall not be described herein any further.

In an embodiment, the method may further include:

step 602 (optional): the user equipment detects a physical downlinkchannel in the control resource set, to determine operations performedon the one or more additional resource sets corresponding to eachcontrol resource set or each group of control resource sets;

and in step 603, a corresponding operation is performed on theadditional resource sets according to the operations determined in step602.

In an embodiment, in step 602, DCI is received by detecting the PDCCH.The DCI includes indication information indicating operations performedon the one or more additional resource sets, and according to theindication information and the format of the information element in theRRC, the operations performed on the one or more additional resourcesets corresponding to each control resource set or each group of controlresource sets may be determined. Reference may be made to Embodiment 1or 2 for a particular implementation of the indication information,which shall not be described herein any further.

In an embodiment, in step 602, the operations performed on each controlresource set or each group of control resource sets may also bedetermined. And in step 603, corresponding operations may also beperformed on each control resource set or each group of control resourcesets.

In an embodiment, when the operations performed are determined as beingdata mapping, PDSCH data are mapped to time-frequency positions of theadditional resource sets and are transmitted; and when the operationsperformed are determined as being rate matching, the time-frequencypositions of the additional resource sets are vacated and rate matchingis performed around the time-frequency positions, that is, schedulingdata contain the additional resource sets, but in assembling transportblocks (TBs), resource blocks at the time-frequency positions of theadditional resource sets need to be vacated.

In an embodiment, the UE may detect PDCCHs in the control resource setsso as to obtain its own RMSI scheduling information, and reference maybe made to existing techniques for a particular method. For example, theuser side determines a particular data resource by detecting the PDCCHs,and receives data to obtain its own RMSI scheduling information.

It can be seen from the above embodiments that by configuring one ormore additional resource sets corresponding to each control resource setor each group of control resource sets, that is, by specificallyconfiguring additional resource sets for the control resource sets,payload of downlink control information may be reduced, and currentlyexisted problems may be solved.
